Done in an official color scheme listed as Cool Grey, Metallic Silver, and Iron Grey, this newest iteration of LeBron’s latest signature sneaker is given a tonal finish consisting of varying shades of Grey. Constructed out of a mesh base and ribbed upper, the major design detail on the upper is without a doubt the sleek Metallic Silver Swoosh logo. You also get a sole unit matching the Grey hue of the upper as well as more Grey hits landing on the branding and lining.
